Logitech wants to help keep your home safe — and push devices like the Nest Cam out of it.

Its new Circle smart camera, which is being launched under the new Logi brand, delivers real-time HD video that lets you monitor your home remotely from an Android or iOS device.

While some people will tell you that tablets are “consumption” devices that aren’t fit for real work, I’d say that’s absolute rubbish. Add a physical keyboard and the right apps, and your tablet is perfectly capable of replacing your notebook computer for a variety of everyday tasks.

I often use my iPad Air for work — and in many ways it makes me more productive. And now Galaxy Tab 4 10.1 owners can do the same thanks to the new Logitech Ultrathin Keyboard Folio, a protective case with a built-in physical keyboard.

Noise-cancelling headphones are suddenly all the rage. It certainly seems as if every big player in the audio game has at least one model that features active noise-canceling, usually accompanied by other luxury features — and with a corresponding luxury pricetag. Even manufacturers who’ve only recently begun making cans, like Logitech UE and Klipsch, prominently feature active noise-canceling in their model lineups.

It may even seem as if the technology has been added to some models simply because it’s become the feature du jour — an impression strengthened by the fact that not all noise canceling is the same. Not even remotely.

None of the headphones in our showdown — the Klipsch Mode M40 ($350), the Logitech UE 6000 ($200) or the Monster Inspiration ANC ($300), the noise-canceling version of the regular, passive Inspiration model we reviewed last year — exhibits the powerful noise-canceling ability that can almost completely drown out noise, like that of the Bose QuietComfort 15. Nor do they sit on the next level down, with NC performance similar to, say, Audio Technica’s ATH-ANC7b (although one here comes close).

Hisense Pulse is a new set-top box powered by Google TV that was first announced at IFA back in August. Its $100 price tag makes it one of the most affordable ways to introduce Google TV to your living room, and it comes with some nice features. If you’ve been waiting to get your hands on one, you can place your order now through Amazon. But you’ll have to be quick if you want it before Christmas.

We’re very stingy with our five-star ratings, and it’s even more rare for us to slap all five onto a gadget.  So pay attention — because today we’re awarding the full five stars to the Logitech UE Boombox ($250), a portable, battery-equipped, eight-driver Bluetooth speaker that sounds absolutely astounding. In fact, the Boombox does a better job of rocking out than some non-portable, home systems costing much more.
